rear differential fluid
I just changed my rear axle fluid on my 03 1500 non lsd .I added about 2 bottlesand alittle of a third of mobile 1.My question is I drove it around the block and came back to check the level and the fluid started to ooze out,did i add too much or do i have to let it set awhile to check?

maybe a little, but not really, what ever is in there will come out to the right level. as long as it is not leaking from around the flange youre mostly ok. make sure it doesnt keep leaking for more than a day or two, if so you might need to get a replacement plug but dont freak if there is a little bit of an oil trail under the plug. you should be fine.

Oil, like most anything, expands when heated. Fill with cold oil to the bottom of the filler hole, then drive around a bit. The diff heats up, the oil heats up and expands. If you pull the filler plug, some oil will come out. This is perfectly okay. Technically, the service manual says to fill to 5/8" below the filler hole. No doubt this is to allow for thermal expansion. Most everyone fills to the bottom of the hole and plugs it up quickly until the next change. In years and years of doing diff oil changes, it's never been a problem.

FSM calls for filling to 1/2 inch below the hole on level ground. Too much fluid can result in foaming. Most Ram guys I know aren't aware of this, fill to the hole, and never have problems. You're probably fine I just wanted to tell you what the service manual calls for.
